Kanstantin Sivtsov kept his tires full Sunday. The rest was easy. Sivtsov, competing in his first race in the United States, survived a rash of flat tires on the streets of Atlanta to win the Tour de Georgia.

Slipstream-Chipotle, the Colorado-based team that features two veteran Tour de France riders, won the rare team time trial fourth stage by nearly 3 1/2 seconds, while Greg Henderson increased his lead Thursday in the Tour de Georgia.
